     Uh... Yeah! Actually, it does, and I don't even own an ST. (SO please:
if my idea is completely off base, sorry for the bandwidth. Please don't
bother with flames.)
     I had a lockup problem not entirely dissimilar with one of my Amiga
systems a while ago, only the "fix" was to pop _any_ diskette out and back
in. The problem turned out to be not software, but a bad CIA chip (Complex
Interface Adaptor; chip that converted disk, serial, keyboard etc output
into something the processor could handle; i.e. an I/O chip) that was
sending noise on the signal lines. Replacing it fixed the problem.
     So here's the question: could this be a similar situation, caused
by excessive RF interference or a bad run of chips? Somebody out there
who likes taking apart their ST systems might want to try improvising
with additional (and removing - see if it happens more) shielding.
                                                     - R'ykandar.
